Novels

The theme of Nazis escaping into space was already evident in Robert A. Heinlein's Rocket Ship Galileo, published two years after the end of World War II, wherein Nazis colonized the Moon after escape from their defeat on Earth. Later books with a similar premise often involve an alternate history featuring the Nazis winning World War II or extraterrestrials traveling back in time to supply advanced technology to one side (usually Germany). Most of Norman Spinrad's The Iron Dream consists of novel written by alternate-history Adolf Hitler who became a science fiction writer, which ends with cloned SS supermen initiating a galactic empire.

In the future solar system of Jack Williamson's "Seetee Ship", the planet Mars is colonized by Nazi Germans and Fascist Italians, and its main public holiday is "Hitler Day" which is often the occasion of bloody riots; the Nazi Mars is one of the malevolent space powers seeking to oppress the book's Liberty-minded Asteroid Belt miners.

Other premises include a splinter group of Nazis (or their ideology) being introduced to a previously benign planet. In some cases the Nazis have merely adapted their already advanced technology to reach the Moon.

Games

The 1988 computer game Rocket Ranger, from Cinemaware, featured a storyline where the Nazis attempted to dominate the world from a lunar base. The gameplay involved using a rocket pack to capture enough equipment to build a rocket, fly to the moon and thwart their plans.

The Black Lance faction in the 1995 game Wing Commander 4 features Nazi-like aesthetic and goals (purification of humanity through constant war and genetic selection via bioweapons).

The term "Space Nazis" was used by fans of the 2004 Killzone videogame to refer to the game's spacefaring enemy faction, the Helghast. The emblem of the Helghast resembles the symbols of far-right nationalist groups like the Afrikaner Weerstandsbeweging and the German Nazi Party, there are notable similarities in helmet shape and officer uniform design between the Helghast and Nazi Germany, and many Helghast weapons bear the German-sounding "StA" acronym in their names. All games in the series have cutscenes of Helghast leaders giving speeches at large rallies, with strong visual and thematic allusions to Nazi rallies.

The now-defunct Stargate SG-1 Roleplaying Game depicted Nazis seizing control of the original Stargate and using it to establish an off-world colony that survived to present day. This was later contradicted by the direct-to-DVD movie Stargate: Continuum, which reinforced the continuity presented in the original Stargate film, depicting the Gate having been shipped to the United States prior to World War II.

The first-person shooter game Wolfenstein: The New Order (2014) said that the Nazis were successfully landed on the moon after their victory in World War II, and they built a base on it. The protagonist William "B.J." Blazkowicz infiltrates the Nazi lunar base in order to steal a nuclear weapon activation code for the resistance.

In Warframe (2013), New Loka is one of the six Syndicates but often called by players the Space Nazis simply because of the main goal of them is to seek the way to restore the humanity through purity, and "Loka" is actually the Sanskrit word for "world". Making New Loka literally mean "New World", just like the Nazis

In the Call of Duty zombies series, Group 935, A Nazi-established research group responsible for the discovery of Element 115 and subsequent reanimation and outbreak of Zombies and also the source of many of the experimental weapons and gadgets found throughout the series, built Griffin Base on the Moon and was accessible via teleporters. In the Ultimis (Original) timeline, the main characters travel to Griffin Base where Edward Richtofen, a former member of Group 935, betrays the others in the group, gaining control of the zombies and the Aether. In an attempt to stop him, the other members of the group launch a barrage of missiles at the Earth, leaving it decimated and fractured, causing Richtofen to lose control over the Aether but maintained control over what zombies remained on Earth. In the Primus (Orgins) timeline, the group travels to a Group 935 facility in Germany named Griffin Castle in order to both kill the Ultimis version of Tank Dempsey and to destroy Griffin Base and Group 935. They succeed in both objectives, launching a barrage of missiles at the Moon (Much like the near-destruction of Earth in the Ultimis timeline), completely destroying it and effectively disbanding Group 935.

Radio, television and movies

The antagonist nation Principality of Zeon in the anime Mobile Suit Gundam is aesthetically based on the Third Reich with similar salute "Sieg Zeon" (also translated as the more grammatically correct "Hail Zeon") and a flag design and remnant movements are called "Neo Zeon". However their actions appear to be based on the Third Reich's ally, Japan, which claimed to be liberating the Asian neighbors they invaded and sought to create a Great East Asia Co-Prosperity Sphere. Zeon similarly gassed other space colonies while proclaiming to be liberating their fellow space colonists from cruel Earth rule and in the Unicorn OVA, Neo Zeon seek to create a "Co-Prosperity Sphere."

Attack from Space (1964): Benevolent aliens from the planet Emerald send superhero Starman to protect Earth from invasion by an evil alien race called the Spherions, warlike creatures of the Sapphire Galaxy. When Starman arrives on Earth, he discovers a conspiracy involving Earth's top scientists, and he must stop the impending alien invasion.

"Patterns of Force", an episode of Star Trek: The Original Series: The Ekosian civilization copied the Nazi Regime to the point of having similar ideologies, clothing, symbols, etc., in an attempt to emulate Germany's rapid economic recovery during the 1930s; their "Führer", a human named John Gill, is in fact a Federation historian and observer who believed that, while Nazi leaders were evil, the system itself was not, and under benevolent leadership could be a highly effective form of government.

The Eastern Alliance, featured in the "Greetings from Earth", "Baltar's Escape", and "Experiment in Terra" episodes of the original Battlestar Galactica television series, is a Nazi/Soviet-like police state government at war with a rival society on an Earth-like planet called "Terra", as well as on many of Terra's "satellite" colony planets elsewhere in space.
